Dodecahedron, Pedagogically Stretched

3D model description

####Dodecahedron Model, Pedagogically Stretched

D is for Dodecahedron

The present design allows students to make their own dodecahedron models and then play around and within it for mathematical insight such as the embedded cubes.

To play with the mathematical ideas, one needs a long elastic cord such as those for name badges (with some hard end covers), 20 vertices, and 30 edges. The inner edges of the connectors are trimmed for easy assembly.

###Among the Files

  1. Edges that come in various lengths, which cannot be mixed up, of course.
  2. Two versions of the vertex.

To assemble a dodecahedron, feel free to press the vertices against some hard surface or use a pair of pliers. Once assembled, it may be hard to take things apart. If so desired, please use the loose vertex or increase the printing resolution.

STEAM educator, learning from and working with K-12 STEAM teachers to explore new ideas of teaching and engagement. I firmly believe ART is at the core of STEM learning or all human learning! I owe my ideas and designs to the hundreds of K-12 children and teachers and university professors I have had the pleasure of working with, in multiple disciplines-- math, science,engineering language arts, social studies, early childhood education and more! All mistakes, of course, are mine! There is no warranty or liability whatsoever implied or explicit behind the designs or ideas. They are all posted for their potential educational values.

When working with children, please strictly observe all safety and health procedures! Please refer to the NSTA safety guides:
